4This invention relates to improvements in oiling devices and 'particularly such devices as are applicable to explosive engines.

p rEhe principal object of the invention isto provide avdevice of this characteuby means spray, and' then .sucked i chambers ofthe engine. 'l .y f.;

@The devicesA heretofore known inthe'art, sofarv as we are awareare defectivein that nto the e explosion gine is not always sufficient to cause'thepoil i Tu ifold.

vtobe sucked up in the formof spray frolnfthe oilcontainer-with any uniformity-of opera` tion. That isrto say,` dueto therelatively Vlarge cross section al area of. the oil .containers heretoforelnown inthis. art, the suction of the pistons was sufficient to fairlywell'cause the flow`v of lubricant so long as the container was full or approximately full ofroihbut due to the relatively large crossV sectional area of theoil container itself, with respect toits depth-` the suction vwould bring up a con` stantly decreasing volume of oil as the level of the oil descended. until finally a point would be reached when the oil level in the container1 was sol low that the device cease to function.

We correct this defect by so arranging the parts that the suction force is directed to a tube or chamber ofrelatively small cross sectional dimensions with the result'that the engine will be lubricated so longas there is any oil in the container at all.

A further Objectis to providea tank havino; a tube of the same height which has an oil'linlet at the lowermostportionthereof, an

Vair inlet opposed to said oil inlet soV that the air and oil may be drawninto theV tube together, and a means for exhausting the air f in the tube above the oil'level to thereby completely lill the tube with aerated oil. f f

i A still further object isY tor inject the'mixture of oil and air into thecenteriof the intake manifold so that the oil will be rthoroughly mixed with the gas and air in the man- The invention is illustrated inthe accompanying drawings, in which: A

the ygasket will 'relievethetube from Vany un- 1 due bending that might tend to crack or break the tube and also provide a sealed connection between the tube and pipe.

The pipe 22 is threaded into the valve at 24, so that the pipe 19 communicates with the pipe 9. Another tube 25, whose lower end is secured within lthe base 2G., `is connected to the tube 19'by means of a passage 26, its upper end passing through the projected `portion 20A, A nut 27 Vhaving airvents 28 `through which air is admitted into the pipe 25, vthence through the passage 26 into the tube 19, is threaded into the portion 20A and is in direct connection with the tube 25; n

The operation of the device is asV follows The container being filled with oil, the engine not running, the oil will be of theisame level in the container, tube19-and tube 25. When the engineis started, thepressure is decreased above tube 19 and container 1. This causes the relatively increased or atmospheric pressure above tube 25 to force the oil in said tube 25 into tube 19 and container l.; Tube 25 terminating below the. lower level of tube 19 and tube v19 being abovev container 11,: the air ,forced in through tube 25 would entirely escape through `tube 19 bubblingfupward through the oil in that tube and carrying with it through tube 15 a certain minute amount of. oil. Due tothe tank 1 being lower than tube 19, the. air will entirely escapethrough tube 19, while the even decrease of pressure overr tube 19and tard(V 1 would, hold the oil at Vthe same level in both.. The oil-laden air is carried through tube 15 and discharged f Athrough the nozzle in the manifold. VThe remation of oil is continually applied to the insuit of this is that a finely dividedspray forterior of the combustion chamber andthe working parts therein. If the end' of the pipe 15, which connects with the intake manifold oil which escapes through the apertures 27d may permeate the entire interior of the man1- fold 16 and be subjected to the upward V'the surface of the oil in the container 1, but,

on the contrary, lift the oil from the relatively small area within the pipe 19 so that the oil. from the container 1- is discharged from the bottom of the container 1 into the pipe 15 and thence into the manifold instead of being discharged from the top, thus insuring a steady flow of the oil at all times instead of a flow which would decrease as the level of the oil descended. The net result is that the oil passes in uniform bubbles and in uniform iiow so long as there is any oil in the container at all. t

What is claimed to be new is:

An -oilinjecting device comprising an oil container, a base portion formed with a conical-shaped depression, a 'tubeseated in said i ond passage from saidy second tube, both of said passages terminating in said conicalshaped depression, whereby the air entering the first tube by the second mentioned passage will not pass through the first mentioned passagebut be directed upward through said first mentioned tube.

16, were flush `with the interior walls of the intake pipe, then ofcourse the oil would flow in thecourse just described, but a portion of it would trickle down the interior walls of the piperl and not be subjected to the upward suction within the pipe 16 with any uniformity. Y

To correct this we provide a hollowY Toasting 27a, counterbored .and internally threaded, as at 2.7, so that the usual pipe 2,7, lead- -jing to the lusual vacuum system, may be threaded into the` counterbored portion 271.
